One Sol-Ark 30K/60K-3P Inverter, One AES Battery Cabinet
When paired with a single Sol-Ark 30K/60K inverter, the AES Cabinet’s maximum continuous current limit is 157 A, operating within its rated 52 / 78 / 104 kW continuous output limit. Actual discharge performance depends on the inverter model’s battery-side power capacity, as shown below.
Full Load Duration (Operation at Max Power)
Inverter Model | Inverter Battery Discharge Limit | CAB-106 | CAB-160 | CAB-210 Estimated run time |
|---|---|---|---|---|
AC Output / Usable Storage / Estimated Runtime | ||||
30K-3P-208V | 30 kW | 30 kW / 104 kWh / 3½ hours | N/A | N/A |
60K-3P-480V | 60 kW | 52 kW* / 104 kWh / 2 hours | 60 kW / 157 kWh / 2½ hours | 60 kW / 209 kWh / 3½ hours |

These run time estimates assume continuous full-power discharge and operation within safe continuous discharge parameters. Final performance should match the site's energy demand and load profile.
System Scalability – One Inverter, One AES Cabinet
Ten Paralleled Inverters
Each Sol-Ark 30K/60K-3P inverter is paired with one AES Cabinet.
In this setup:
104/209 kWh of usable backup energy per inverter
Discharge power limited by the inverter model (30/60 kW)
Up to ten inverters can be connected in parallel on the backup side, providing up to 300-600 kW of continuous backup power and approximately 1.06–2.12 MWh of total backup energy (10 × 104 kWh / 10 × 209 kWh).
Grid-Tied (Non-Backup) Scalability
The number of inverters or batteries is unlimited for non-backup use. Each inverter runs independently, allowing systems to scale as large as needed for energy shifting, peak shaving, or other grid-interactive applications.
DC Battery Wiring - One Inverter, One AES Cabinet
The inverter’s battery input terminals are connected to the AES Cabinet using two pairs of 50 A conductors (two positive and two negative cables).
Inverter to Cabinet DC Wiring
Each Sol-Ark 30K/60-3P inverter has two battery input terminals, each rated up to 50 A. The AES Cabinet connects using two positive and two negative conductors, each protected by a 70 A fuse in the AES Cabinet’s built-in DC distribution box.
This setup ensures balanced current flow to each of the inverter’s internal DC/DC converters and supports continuous discharge of 30 or 60 kW.
Communication – One Inverter, One AES Cabinet
Inverter - LYNK II - Cabinet Communication
In a one-to-one configuration, the AES Cabinet communicates with the Sol-Ark inverter through the LYNK II Gateway, enabling real-time, closed-loop control.
Use standard CAT6 or higher Ethernet cables, wired in a straight-through configuration with RJ45 plugs on both ends.
Connect one cable from the LYNK II’s CAN port to the Sol-Ark inverter's BMS1 port.
Connect a second cable from the LYNK port on the LYNK II Gateway to the J3/J4 port on the AES Cabinet’s High Voltage Box. On most AES Cabinets, a CAT6 cable is already connected to the J3 port on the AES Cabinet’s High Voltage Box and is accessible from the LYNK II.
This communication link enables the inverter to receive live battery data, including state of charge, voltage, current, temperature, and charge/discharge limits, for safe, accurate, and optimized operation.
